Which disorder is characterized by the presence of one or more neurological symptoms that have no organic cause?

The choice of conversion disorder accurately captures the essence of the question, as this condition is defined by the manifestation of neurological symptoms—such as weakness, sensory loss, or episodes resembling seizures—that cannot be traced back to any discernible organic or medical cause. Individuals with conversion disorder often experience these symptoms following psychological stress or trauma, reflecting the complex interplay between the mind and body.

This disorder highlights the mind's ability to produce physical symptoms in response to emotional conflicts or distress. For example, a person experiencing significant emotional trauma might develop paralysis or other neurological issues without any underlying physical injury or disease. The key distinction in conversion disorder is that the symptoms are not intentionally produced or feigned; rather, they arise as a legitimate reaction to psychological distress.

In contrast, the other options pertain to different psychological issues, such as exaggerated concern about body image, chronic physical complaints with no clear medical explanation, or generalized anxiety symptoms without a specific focus. These conditions do not center primarily on the emergence of neurologically-themed symptoms devoid of clear medical underpinning, which is central to conversion disorder. Thus, the correct response encompasses the unique nature of conversion disorder and its neurologically oriented symptoms without an organic basis.
